Ok, so it probably won't for you. If you look here you'll see that my bot automatically votes on content. However, everyone is limited in the amount of times they can upvote per day. After each upvote, you lose some of your voting power. Your rewards are proportional to your voting power. So if you vote too much for no reason, you'll end up having no curation rewards.
Here, I'm arguing that no matter what I vote on, my bot will always be doing better than me at identifying what will end up being popular. By voting manually, I'm lowering my voting power, which will lower my potential rewards (due to my bot) in the long run.
Hope this clarifies it all. Thanks for the comment!
